Document Description
The purpose of the Reclamation District No. 1001 (RD1001) Pipe Replacement Project(Proposed Project) is to replace two pipes connected to auxiliary discharge pumps at the terminus of the Main Drain. The existing discharge pipes connected to the two auxiliary pumps are 36-inch and 42-inch diameter steel pipes that have two major issues. The first issue of concern is that the pipes cross through a levee below the 100-year water surface elevation and have inadequate siphon-breaks and closure structure that my cause water to siphon back through the pipe if the pumps fail during a 100-year event. The second issue is that the pipes have been in use for 50 years and, upon inspection, have been found to be extremely thin and corroded in multiple areas. The corrosion and inadequate closure structure result in a significant risk of pipe failure during a flood event, which would result in backup of the Main Drain and flooding to the RD1001 property. In addition, failure of these pipes would also threaten the integrity of the Natomas Cross Canal levee. These are critical flood protection utilities that need to be improved.
